3 For Safety WARNING 1. ALWAYS refer to the operation manual when working near locations at which the alert mark shown on the left is attached. If the advice in the operation manual is not followed there is a risk of personal injury or reduced equipment performance. The alert mark shown on the left may also be used with other marks and descriptions to indicate other dangers. 2. IEC Standard The IEC standard specifies four categories to ensure that an instrument is used only at locations where it is safe to make measurements. This instrument is designed for measurement category I (CAT I). DO NOT use this instrument at locations specified as category II, III, or IV as defined below. Measurement category I (CAT I): Secondary circuits of a device that is not directly connected to a power outlet. Measurement category II (CAT II): Primary circuits of a device that is directly connected to a power outlet, e.g., portable tools or home appliance. Measurement category III (CAT III): Primary circuits of a device (fixed equipment) to which power is supplied directly from the distribution panel, and circuits running from the distribution panel to power outlet. Measurement category IV (CAT IV): Building service-line entrance circuits, and circuits running from the service-line entrance to the meter or primary circuit breaker (distribution panel). 3. Laser radiation warning NEVER look directly into the cable connector on the equipment nor into the end of a cable connected to the equipment. There is a risk of injury if laser radiation enters the eye. The Laser Safety label is attached to the equipment for safety use as indicated in "Laser Safety" later in this section. iii

4 For Safety WARNING Electric Shock 4. To ensure that the instrument is earthed, always use the supplied 3- pin power cord, and insert the plug into an outlet with an earth terminal. If power is supplied without earthing the equipment, there is a risk of receiving a severe or fatal electric shock or causing damage to the internal components. Repair 5. This equipment cannot be repaired by the operator. DO NOT attempt to remove the equipment covers or unit covers or to disassemble internal components. Only qualified service personnel with a knowledge of electrical fire and shock hazards should service this equipment. There are high-voltage parts in this equipment presenting a risk of severe injury or fatal electric shock to untrained personnel. In addition, there is a risk of damage to precision components. Calibration 6. The performance-guarantee seal verifies the integrity of the equipment. To ensure the continued integrity of the equipment, only Anritsu service personnel, or service personnel of an Anritsu sales representative, should break this seal to repair or calibrate the equipment. If the performance-guarantee seal is broken by you or a third party, the performance of the equipment cannot be guaranteed. Be careful not to break the seal by opening the equipment or unit covers. Falling Over 7. This equipment should always be positioned in the correct manner. If the cabinet is turned on its side, etc., it will be unstable and may be damaged if it falls over as a result of receiving a slight mechanical shock. Always set up the equipment in a position where the power switch can be reached without difficulty. iv

5 For Safety CAUTION Fuse Replacement 1. Always remove the mains power cable from the power outlet before replacing blown fuses. There is a risk of electric shock if fuses are replaced with the power cable connected. Always use new fuses of the type and rating specified on the rear panel of the instrument. There is a risk of fire if a fuse of a different rating is used. T2A indicates a time-lag fuse. Cleaning 2. Keep the power supply and cooling fan free of dust. Clean the power inlet regularly. If dust accumulates around the power pins, there is a risk of fire. Keep the cooling fan clean so that the ventilation holes are not obstructed. If the ventilation is obstructed, the cabinet may overheat and catch fire. v

6 For Safety Class 1, 1M indicate the danger degree of the laser radiation specified below according to IEC :2001. Class 1: Lasers that are safe under reasonably foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing. Class 1M: Lasers emitting in the wavelength range from to 4000 nm that are safe under reasonably foreseeable conditions of operation, but may be hazardous if the user employs optics within the beam. Two conditions apply: a) for diverging beams, if the user views the laser output with certain optical instruments (for example, eye loupes, magnifiers and microscopes) within a distance of 100 mm; or b) for collimated beams, if the user views the laser output with certain optical instruments (for example, telescopes and binoculars). Class I, IIa, II, IIIa, IIIb indicate the degree of danger of the laser radiation outlined below as defined by 21 CFR :1995. Class I: Class I levels of laser radiation are not considered to be hazardous. Class IIa: Class IIa levels of laser radiation are not considered to be hazardous if viewed for any period of time less than or equal to seconds but are considered to be a chronic viewing hazard for any period of time greater than seconds. The wavelength range of laser radiating is in 400 to 710 nm. Class II: Class II levels of laser radiation are considered to be a chronic viewing hazard. The wavelength range of laser radiating is in 400 to 710 nm. Class IIIa: Class IIIa levels of laser radiation are considered to be, depending upon the irradiance, either an acute intrabeam viewing hazard or chronic viewing hazard, and an acute viewing hazard if viewed directly with optical instruments. The wavelength range of laser radiating is in 400 to 710 nm. Class IIIb: Class IIIb levels of laser radiation are considered to be an acute hazard to skin and eyes from direct radiation. vi

This may cause permanent damage to the equipment such as a burnout of the optical receiver and ferrule end panel. [3] Analog signal output connector An SMA connector for analog output with an output range between 0 and 2 V and output impedance of approximately 1 kω. This connector outputs a voltage proportionate to the optical input. The connector outputs a voltage of approximately 2 V when light at the full scale level of each measurement range is intercepted.* *For example, this means optical input of -10 dbm when the range is set at 10 dbm. Caution The analog signal output connector is exclusively for output. When signals are input by mistake, this may cause damage to the Device or the signal source connected. Do not pull the cord while the cord remains inserted to the analog signal output connector. This may cause damage to the connector or the internal circuit. 2-11

42 Section 2 Nomenclature and Function Point Analog signals are directly output without correction of the wavelength sensitivity of the signals from the light intercepting circuit of the optical sensor. For this reason, the relationship between the level indication and the voltage output merely serves as a guideline and they do not necessary match each other. However, this function will prove useful to observe changes that take place more quickly than the display of numerical values on the main unit is able to indicate.

44 Section 2 Nomenclature and Function Point Analog signal output is directly output to the optical sensor without correcting the wavelength sensitivity for the received optical circuit signal. Therefore, the relation between the displayed level and the output voltage is a rough guide, and is not necessarily equal. However, it is effective in observing the more minute change than the numeric value change displayed in the main unit. [3] Pulling-lever The lever has a lock mechanism when the sensor adapter is installed in the main unit. When removing it, pull it out holding the lever.
